WHIRL FOR SPlNNlNG-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 394,265, dated December 11, 1888.

Application filed June 21, 1888- Serial No. 277,774. (No model.)

To all whom it may concern:

Be it known that I, THoMAs HALL, a citi- Zen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in \Vhirls for Spinning- Spindles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in spinning-m'achine whirls; and my object is to so improve these whirls that the flanges are not liable to be fractured or otherwise injured under ordinary usage. I attain this object by the means illustrated in the annexed drawings, in which Figure 1 is a side view of a spindle having my improved compound whirl applied to it; and Fig. 2 an enlarged diametrical section of the lower part of a spindle, showing the peculiar construction of my improved whirl. Fig. 3 is a diametrical section showing the modification of Figs. 1 and 2 hereinafter explained.

Similar letters refer to similar parts in all the views.

The letter A designates a tubular spindle having an annular flange, a, and provided with a stud, c, the latter to key the spool to the spindle, so that the spool will rotate with the latter in the usual well-known manner. Below the flange a, and integral with the spindle-tube A, is a tapered enlargement or boss, A. (Shown clearly in Fig. 2 of the annexed drawings,) On this boss I rigidly secure my improved whirl B. This whirl has before my invention been made integral and of cast 1 metal. In practice I find that the upper flange when the whirl is so cast is frequently broken by reason of the fragility of the cast metal. To effectually obviate this objection,

I first drive the metal washer or flange c on the boss A of the tube A. I then drive the boss A of the tube A into the central aperture through the body (I and base-flange c of the whirl B.

It is obvious that both flanges e and c of the whirl B may be made of a comparatively tough metal or other suitable material, and the body (Z of a less fragile mctalthat is to say, when both flanges e and c are made of a less fragile metal than the body portion (Z the lower flange, 1:, may be held tightly upon the lower reduced end of the body (I by friction or in any other suit-able manner, and a portion, C driven upon the tapered boss A, as shown in Fig. 3.

It will be observed from the foregoing that I produce a spinning-whirl having an independent flange which is not adjustable and which not liable to be broken; also, that I produce a whirl one or both flanges of which may be readily replaced, if necessary. Furthermore, it will be seen that by my invention the old and well-known whirls having broken flanges can be utilized by cutting oif the useless flanges and substituting more perfeet and more endurable ones.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A spinning-1nachine whirl having a flange or washer formed separate from the body (I, both being adapted to be applied to a tubular spindle, as specified.

2. The combination, with the tubular spindle, of a whirl composed of a body, d, and flanges formed separate therefrom and united upon the boss of said spindle, as specified.

3. The within -described spinning-whirl having a body and a flange formed of cast metal in one piece, and a flange formed of wrought metal, substantially as described.

4. The combination, with the tubular spindle having a flange, a, and a boss, A, of a whirl composed of a cast-metal body and flange and a wrought-metal flange, e, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS HALL.
